QPC油田王家沟油区延长组长4+5沉积微相研究

Study on sedimentary microfacies of Yanchang Formation 4+5 in Wangjiagou oil field of QPC oilfield

石油作为不可再生资源,其生产量远远不能满足市场需求。为了应对能源危机,必须有效提高石油的勘探开发产量。在前人研究的基础上,通过对王家沟油区的主力产油层长4+5油层的岩心资料进行深入剖析,详细划分了该油层沉积相。并对其砂体展布特征进行细致描述,为后续的勘探开发工作提供了重要依据。

As a non renewable resource,oil production is far from meeting market demand.Therefore,in order to cope with the energy crisis,it is necessary to effectively increase the exploration and development production of oil.On the basis of previous research,this article conducts in-depth analysis of the core data of the Chang4+5 oil layer,the main oil producing layer in the Wangjiagou oil region,and divides the sedimentary facies of this oil layer in detail.And a detailed description of the distribution characteristics of its sand bodies provides an important basis for subsequent exploration and development work.
